Planes contribute 9% of the worldâs carbon pollution, but electrifying them has always seemed impossible; batteries have never been powerful or light enough to carry themselves. But in 2023, batteries reached a tipping point in power and weight. Beta Technologies, based in Vermont, is flying its six-passenger vertical-takeoff airplanes every day. David Pogue was there at takeoff.

The U.S. has fallen into polarized, partisan, political bickering. Online, liberals and conservatives seem to despise each other. But nobody seems to stop to ask: How did we get our liberal and conservative views in the first place? We formed our opinions by carefully weighing the issues and thoughtfully choosing a stance, right? Well, no; turns out over half of our political leanings are determined, incredibly, by our genes. In this episode: How we figured that out, and what it means for our future.

Every month, over a billion people open their phones and fire up Google Maps. Its original functionâoffering driving directions, with real-time traffic trackingâwas disruptive enough in 2008, when most people had to pay $10 a month for traffic data. But since that time, itâs become a global business directory, a transit timetable, crowdedness monitor, a Street View miracleâand now, in its newest release, an augmented-reality viewer of the cityscape around you. The question is: How is Google doing it, and why is it free? Meet the man who runs Googleâs entire Geo division.

For the most part, we donât hunt whales anymore, but weâre still killing themâmostly by driving ships into them. One species, the North Atlantic right whale, is now extinct in most parts of the world; only 340 are left. But it may not be too late. An extraordinary coalition of nonprofits, research institutions, foundations, and even megalithic shipping corporations are teaming up to develop technology, prove the science, and, yes, save the whales.

On Christmas Day, 2021, NASA launched the James Webb Space Telescope into orbit a million miles from Earthâa huge and insanely ambitious machine, billions of dollars over budget and 14 years past deadline. Now, as the telescope completes its first year of capturing astonishing images of the universe as it was just after the Big Bang, its creators discuss why so many things went right.

People use all kinds of words to describe Elon Musk, from âgeniusâ to âmegalomaniac,â from âvisionaryâ to âerraticââbut now thereâs less reason to call him âenigmatic,â thanks to Walter Isaacsonâs new 688-page biography. Isaacson hung out with Musk for two years, attending meetings, witnessing meltdowns, taking Muskâs 3 a.m. phone calls. In this special âUnsung Scienceâ episode, Isaacson describes the man behind Tesla, SpaceX, Starlink, and the social-media site once known as Twitter.

In April 1978, MIT professor Amar Bose was flying home to Boston from Switzerland. But when he tried to listen to music through the airlineâs headphones, he couldnât hear a darned thing. He spent the rest of the flight doing acoustical mathâand sketching out an idea for headphones that literally subtracted background noise from what you hear. Today, noise-canceling headphones are everywhere. But the revolution began with Amar Boseâs airplane sketchesâand the 22-year, $50 million journey that led them to the ears on your head.

Thereâs a new kind of jack in townâwell, new as of 2014âcalled USB-C. This single, tiny connector can carry power, video, audio, and data between electronic gadgetsâsimultaneously. It can replace a laptopâs power cord, USB jacks, video output jack, and headphone jack. The connector is symmetrical, so you canât insert it upside-down. Itâs identical end for end, too, so it doesnât matter which end you grab first. USB-C has the potential to charge your gadget faster and transfer data faster than whatâs come before, too. And the brand doesnât matter. My Samsung USB-C cable can charge your Apple MacBook and his Surface tablet. The only question left: Where did it come from? Who invented it? And why?

Genealogy has been around a while. So has DNA evidence. But what if you combined the two? What if you could use DNA from a crime scene, compare the unknown killerâs genetics with public databases of other peopleâs DNA, figure out who his relatives are, and thereby determine his identity? Thatâs the system that CeCe Moore invented five years ago. So far, sheâs cracked over 270 cold cases using this methodâand brought closure to hundreds of grieving families.

Weâve known about the placebo effects for over 200 years. Thatâs where doctors give you a pill containing no actual medicine, but you still get better. Recent studies have uncovered a broader range of benefits from the including alleviated pain, nausea, heart rate, hay fever, allergies, insomnia, depression, anxiety, fatigue, and even symptoms of Parkinsonâs. Weirder yet, the characteristics of the pill â color, size, and shape â influence their effectiveness. Fake capsules work better than fake pills, and fake injections work best of all. The question is: Just how far can fake treatments go?

In 1994, Masahiro Hara got tired of having to scan six or seven barcodes on every box of Toyota car-parts that zoomed past him on the assembly line. He wondered why the standard barcode from the 70s was still used...Why couldnât someone invent a barcode that used two dimensions instead of one that could work from any angle or distance, even even if it got smudged or torn?
And so, studying a game of "Go", he dreamed up what we now know as the QR Code â the square barcode you scan with your phone. It shows up on restaurant menus, billboards, magazine ads â even tattoos and gravestones. But even that, says Hara-san, is only the beginning.

In his senior year of college, a monstrous ailment fell upon Doug Lindsay. His skin felt flayed. His heart raced. The room spun. He was so weak, he couldnât sit up in bed, let alone walk. Worst of all, doctors had no idea what was wrong with him.
Only one person on earth had the time and motivation to figure out what was wrong with Doug Lindsay: Doug Lindsay. Over the next 14 years, he consumed medical textbooks and science journals. He attended medical conferences in his wheelchair. He wrote polite, well-informed letters to specialists all over the world. In the end, he not only figured out what was wrong with himâhe invented a new surgery that he thought would fix it. He was right.

Weâve been shipping stuff across oceans for centuries. But until 1956, we loaded our ships in the dumbest way possible: one at a time. Then Malcolm McClean came along. He envisioned lifting the big metal box part off a truck and setting it directly down onto a ship. Every one of these boxes would be identical and interchangeable, maximizing space and minimizing waste. The shipping container was born â an idea that was so powerful, it rejiggered the global economy, gutted cities, and turned China into the worldâs manufacturer.

The first time you heard âStar Trekâ characters speak Klingon, or the âGame of Thronesâ characters speaking Dothraki and High Valyrian, you might have assumed that the actors were just speaking a few words of gibberish, created by some screenwriter to sound authentic. But these are complete languages, with vocabulary, syntax, grammar, and even made-up histories. Thereâs only one person on the planet whose full-time job is creating themâand these days, heâs swamped with requests. No doubt about it: Conlangs (constructed languages) are the new special effect. Me nem nesa!
Hear from David Peterson (author, linguist & full-time language maker), Mark Okrand (author, linguist & creator of Klingon), and Angela Carpenter, (linguistics professor at Wellesley College).

Weâre overrun with plastic. Itâs in our oceans, our water, our food. Something has to be doneâpreferably by corporations, which churn out millions of tons of plastic every year.
Enter: the toothpaste tube. It might seem like a minor player in the plastic problem, but we throw 20 billion toothpaste tubes into the landfill every year. Recycling plants canât take them, because theyâre made of plastic and metal foil bonded together. They all end up in the landfill.
Colgate, the #1 toothpaste brand, decided to tackle the problem. It spent five years and millions of dollars to design a tube made of the same plastic milk jugs are made ofâthe easiest-to-recycle plastic in the worldâwith no metal foil. The new tube is indistinguishable from existing tubesâexcept the whole thing can go into the recycle bin.
And thenâColgate gave away the patent. Today, 90% of the worldâs toothpaste makers are switching to recyclable toothpaste tubes. This is the uplifting, surprising, and slightly hilarious story.

Understandably, there is a lot going on in our lives, and we feel pulled in every direction. But trying to get everything done can distract from the joy that surrounds us. Host Shankar Vedantam and psychologist Dacher Keltner discuss what it means to savor the beauty of the people, moments, and things in the world and the scientific reasoning behind the feeling of "awe."
This is an episode of Hidden Brain that originally aired in February 2023, and you can listen to new episodes of Hidden Brain wherever you get your podcasts.

After 17 years of trying to prop up their failing farm outside of London, Charlie Burrell and Isabella Tree were stressed, exhausted, and $1.7 million in debt. They decided to stop farmingâno more plowing, planting, irrigating, chemicals. They gave away the farmâto nature.
20 years later, their land has one of the most important biodiversity hotspots in the UK. These 3500 acres teem with species, many of which are endangered or hadnât been seen in the UK for centuries. And the twist: Their land now generates more money than it ever did as a farm.
Similar rewilding experiments are under way in 30 countries. They offer protection for nearby farms, corridors of safety for animalsâand buffers against climate disasters for us.

65 million years ago an asteroid struck the earth. In the ensuing planetary darkness, the dinosaurs went extinct. But the dinosaurs didnât have a space program! Now we can spot incoming asteroids with steadily improving confidence. If we see one on a collision course with the Earth, we know from the movies that the solution is to nuke it...Right? Actually, NASA has a better idea. If you can just nudge an asteroid slightly off its current path, maybe 25 or 50 years before it hits us, it wonât hit the earth. It will sail harmlessly past us. In 2022, NASA put that idea to the test. It sent a tiny spacecraft 7 million miles into space, for the express purpose of crashing into a known asteroidâto see if we could bump it into a different path. We quickly found out. This is the story of the DART (Double Asteroid Redirection Test) mission.
Hear from Dr. Richard Binzel, MIT professor. Dr. Elena Adams, lead engineer for NASAâs DART mission, and Dr. Lori Glaze, director of NASAâs planetary science division.
